A Spam festival, cocktail lounge seating and 25th anniversary promotions are all in the cards for the Inland region’s three Class A minor league baseball clubs in this upcoming season.

Each of the teams — The Inland Empire 66ers of San Bernardino, Rancho Cucamonga Quakes and the Lake Elsinore Storm — will roll out a cornucopia of improvements and promotions, many with the manic edge for which the minor leagues are renowned.

Among the regular features at 66er home games at San Manuel Stadium in San Bernardino will be $3 Dollar Thursdays and First Responder Sundays. The organization plans to install a beer garden along the third base line.

On July 5, the team will throw a party for Spam’s 80th birthday that will include a Spam-eating contest and ballpark Spam treats.

“We’re excited about it,” General Manager Joe Hudson said. “It should turn out to be a great season.”

The new season — and new name — come after the team signed a new 10-year lease with the city. As part of that deal, the city has agreed to pay up to $2 million for repairs and maintenance at the stadium.

Neither the Quakes nor the Storm have announced their season-long promotions lineup yet.

The Quakes, however, promise a full slate of attractions based around the club’s 25th year in existence. The team recently unveiled its 25th-anniversary logo that will be incorporated into promotions, merchandise and caps.

As it does every year to preview the season, The Storm will host its annual Sip ‘n’ Swing celebration, including guests taking batting practices, a children’s FunZone and Beer and Sausage Fest, at The Diamond stadium on March 19. Contrary to previous announcements, the event will not include Chargers’ pinata bashing, which has been postponed until later in the season.

In addition to Sip ‘n’ Swing, the Storm is cranking up the season with a perhaps unconventional approach for the minors — baseball.

The Storm will square off against their parent club, the San Diego Padres, on March 31, and will host a game between San Diego State University and UCLA on April 4.

The games will showcase the stadium’s new seats and seating arrangements. Since opening in the mid-1990s, the stadium had relied on the same plastic chairs until the city, which owns the stadium, decided to replace them this year.

In doing that, they also came up with some innovative sections, including a bowl behind home plate that will feature cocktail lounge-like tables and an area above the dugout section featuring four padded chairs around a table in a private area, with cocktail service.

“We’ve stayed true to the original spirit of the facility while creating new hangout areas for our fans young and old,” General Manager Raj Nayaranan said in a release.

The attention to the fan experience and game environment is one reason why the three franchises have thrived along with the league’s five other teams.

In contrast, after being California League affiliates for years, the organizations behind the High Desert Mavericks in Adelanto and Bakersfield Blaze left for the East Coast primarily because of deteriorating stadiums.

“While we feel bad for the fans in those communities, the bottom line is those stadiums needed some help,” said Mike Lindskog, the public relations director and announcer for the Quake.

Under the leadership of Dave Oster, the Storm became the league’s annual attendance leader. Yet, Oster, who is now a minor-league consultant and promoter, said Bakersfield would be the league’s biggest market if it had a better stadium.

“If you put a new stadium up there, you’d probably run Elsinore’s numbers out of the water,” he said.

With the departure of High Desert and Bakersfield, the 76-year-old league is down to eight franchises for the first time in at least three decades, President Charlie Blaney said.

Yet, he believes the reduction is the proverbial blessing in disguise.

“We’ve had concerns with both Bakersfield and High Desert for various reasons, which was why those teams were realigned out of California,” he said. “We’ve got eight solid franchises with no concerns and no problems, and it’s a natural fit because all of the eight western major league franchises are affiliated with the eight teams in our league.”

Having parent organizations closer to their minor-league teams is better for player development, rehab and internal transactions, he said. Eastern major-league clubs typically won’t maintain a western minors affiliate for more than a few years, he said.
